- 1 CGT is the extra income tax the discounted gain adds on top of your other income. Resident individual. Estimate only.
The 50% CGT discount
Australian resident individuals who own an asset for at least 12 months pay tax on only half the gain. Sell inside 12 months and the whole gain is taxed at your marginal rate, so it's often worth waiting for the anniversary if you're close.
Common questions
Do I pay CGT on my family home?+
Generally no, your main residence is usually exempt. CGT typically applies to investment properties, shares, crypto and other investments.
Can capital losses reduce my CGT?+
Yes. Capital losses (this year or carried forward) are subtracted from your gains before the 50% discount is applied. This estimate assumes no losses, so add them in your return.
